'Be it known .that,I, ALPHONSE BAzIN, a German citizen of the -UnitedStates, residing at Swampscott, in thecounty `of vEssex and StateofMassachusetts, haveinvented new and useful Improvements in- Nut-Locks,of which thefollowing is a specification.

This invention relates to improvements in locking devicesby which a nutis held from turning or jarring loose from a bolt to which it isapplied, and the improvement resides in the construction, combinationand arrangement of parts set forth in the following specification andfalling within the scope of the appended' claim.

In. the 'accompanying drawings: Figure'l is a front elevatlonillustrating my improved lock in engaging position upon a nut,Fig. 2 isa sectional-:viewon the line 2-2 of Fig. 1, Fig. 3 isla viewillustratingthe manner in which the locking device may be removed fromthe but Without necessitating the entire-removal of the retainingscrews, and Flg. e' 1s a perspective view ofthev improvement. y .l Inthe accompanying'drawings, the nume1' a11 designates a bolt, 2 anutand 3my improved locking plate. The plate embodies-what may be termedarounded head 4, which is formed with a polygl'onal opening, `and the-wallsprovided by tie opening are formed with depressions or notches 5,whereby the plate .may 4be arrangedl upon various sizes and shapes ofnuts. The plate 3 is constructed from a flat strip of resilientvmaterial and its portion extending'from its head 4 is formed with adepression 6 which is centrally provided with a slot 7 ,the said slotopening at one side of the plate 3; Adapted to be received within thedepress vsion '6 is aheaded screw-8, the threaded shank of thescrewpassing between the walls formed by the sl0ts-7 so as to permit ofits head tightly compressing against the inner wall formed by thedepression 6. It will be noted that the depression is arrangedconcentric of the bolt 1,'and that its opposite end walls are rounded,the end walls ardenkst#l this pstent may bs obtsixied tor rangedadjacent the entrance of the slot 7 being intersected by the said slot,and the said ends contact with the head to prevent fthe plate beingaccidentally removed from the nut.. However, when-it is desired. toremove the pla-te without removing the screw 8, the screw may beloosenedsufficient to raise its head above the depression 6 and the platemay.,then be turnedupon and with the nut to the position illustrated in Fig.3,

and an outwardmovement of the plate will remove the same from thev nut.l The plate may be employed in. lieuof a bwrench for removing the n'utfrom the bolt, in which instance the screw 8 is entirely withdrawn,

and the plate, still engagingwith the nut,

is rotated in an unscrew'ing` direction, and

to facilitate such removal of the nut bythe Y plate, any instrumentsuchas an .ordinary nail punch or the-like mayl Lbe inserted within theslot 7 .t0` .contact with the. inner wall of the sa1d`slot,the saidinstrument thus serving as a handle for the plate. A.

Having thus described-the invention, what `I. claim is: I

In combination 'with it bolt` and a nut therefor, of a'v locking plate,saidl locking plate including a head' havinga plolygon-al opening,l theinner edges`- ofw ich are formed with subst'antdaily` Vfshapednotches,the plate below its head being formed with a rounded depression and-thesaid depressed .portion being centrally. provided witha slot whichenters the de ression from one' of the side edges of the p ate, thedepression hav.-

wall of the'depression, substantially las and for the purpose set forth.

In testimony whereof I'aitix my signature in presence of two witnesses.d i y ALPHONSE BAZIN.
